Lese has released Codec v2.0, a free lo-fi plugin for macOS and Windows that simulates lossy audio compression artifacts, updated with new features like Packet Disorder, Noise, and Crunch.
If you’ve followed BPB for a while, you already know how much I loved the original Codec. It’s one of the few plugins that replicates the nostalgic (if you grew up in the early 2000s like me), low-bitrate MP3 artifacts characteristic of early digital audio compression.
Unlike a traditional bitcrusher that harshly reduces bit depth and sample rate, Codec emulates the subtler degradation of compressed internet audio—think poor-quality voice calls or a heavily compressed 128 kbps MP3.
The original Codec stood out because it was the first freeware plugin that let you recreate these types of compression-based audio imperfections in a DAW. There’s also excellent Lossy ($79) from Goodhertz, but it’s not freeware, although definitely more feature-packed.
The new Codec 2.0 takes things further than the original. My favorite new feature is Packet Disorder, a glitch-style effect that randomly shuffles incoming audio packets, creating chaotic and unpredictable textures.
This isn’t the smooth, lossy degradation we’ve come to expect from Codec—it’s glitchy and erratic, and I absolutely love the results.
The Noise module adds a layer of colored noise before compression, which enhances the plugin’s lo-fi character. This makes everything sound even more “broken,” but in a good way. I loved it on analog-style pads. You can control the tonal range of the noise, making it a versatile tool for shaping the texture of your sound.
Lastly, Crunch adds a distortion element. It’s activated by hovering the visualizer at the top of the GUI, which is a cool touch. Personally, I find the distortion less useful than the other features, but some users will enjoy the added grit.
Codec is still one of my go-to tools for adding digital texture to pads, drums, or even bass. It delivers a nostalgic lo-fi aesthetic that feels perfect for vaporwave, dreamcore, or any “nostalgiacore” genres that thrive on retro digital and analog sounds.
The pastel-colored GUI remains largely the same—intuitive, clean, and just plain gorgeous. Some of the controls were shifted to the left, and new controls have been added, but the core layout hasn’t changed.
Codec v2.0 is still available as a free download from the developer’s website. You’ll need to provide a valid email address to get the plugin, which comes in VST3, AU, and AAX formats for Windows and macOS.
